. My invention relates generally to internal means for supporting the automatic pressure valve-j which is" sometimes used in such engines.

-On. 's ome motor vehicles, particularly of the runabout type, it is'necessary to lojcate the gasolene tank so-low that it-is impossible to supply the gasolene to the engine by gravity, and therefore some automatic pressure system must be employe In. such motor vehicles there has been. employed an automatic pressure valve connected with-the exhaust from the engine, ,whereby that exhaust furnishes the motivefpower" for foreing the gasolene under uniform pressure to 25 the engine. In such systems the automatic pressure valve has ordinarily been mounted "either upon the dashboard of the machine, or upon the frame.of the engine, and this pressure valve has been connected by to the'exhaust from the engine, The objectoflthe present invention is to provide a simple contpact and. convenientmeans for supporting he pressure valve and -at the same timeconnecting it with'the ex-- haust; 1

porting means a simple and etficient form ofstrainer throughwhich the exhaust must ass before it reaches the pressure va ve.

exhaust pipe of'theengine which is provided withla boss-2 surrounding an open ng in the pipe. 1 Mounted-upon: this, .bossa'nd con- ,nectedthereto ina'ny suitablemanner is" the bracket whichlis tubular in form, the diameters, the diam eter of-the lower part being less than that of i the upper part; Extending up through the. opening inthe exhaust pipe Sand into-the lowerpart of the'brac iket 3 is thelpipe 4, the lower end of which may" be bent sofas to" facein the direction fromwhichthe exhaust frojmthe engine comes. This bend: in the pipe is not necessary, but when used-it is for i effectively receiving to the pressure valve the pulses tie 'to the, exhaust of the engine. The upper end of the bracket 3' is-provided with screw threads 5 which receive corresponding screw threads on the tubular plug 6. This tubular plug 6 is 'el osed at its upper end, is provided with a flange 7 which fits on top ofgthe bracket 3, and is also provided with the 'angularpr'ojection Sfor the purpose of facilitating its removal.v The tubular port-ion below the closed end is provided with' perforations or openings 9, and -the lower end of this tubular plug fits; closely a shoulder 19 'on the interior of the bracket 3 conforming to its shape is the foraminous screen 11 which, may be made of'wire gauze, or finely per forated sheet metal. I

Connected with theuupper part of the bracket '3 and preferably nade integral therewith is thep'art 12 of the bracket which furnishes the passage for the exhaust to the automatic pressure valve 18. The part-12 is connected tothe pressure .valveby the machined joint. 14, 15 and the bolt16. The particular form of the pressure valve is not shown, since it forms 'no part of the present I invention. The invention is applicable. to various forms of pressure valves. The part '12, may be placed at any angle to the part 3 which seems most convenient in the particular arrangement of parts of the engine with which it happens to'be used.

It is believed that the purpose, function of the bracket, as Well'as its advantages, will beobvious from the above description of the construction. Its purpose is to simplify and improve the connection between the pressure valve and the exhaust. The purpose of the straineris toremove the carbon and othei impurities in the exhaust gas as it passes to the pressure valve, and

the advantage of the particular form shown is its simplicity and effectiveness.

I WVhat I claim is:

1.- In an internal combustion engine, the combination with the engine exhaust pipe, of a hollow bracket thereon and communieating therewith,a removable plug arranged 2. In internal combustion engines, the

combination with the engine exhaust. pipe, of

a hollow angular bracket mounted thereon and communicating therewith, a tubular plug with closed outer end arranged in bracketat the angular bend thereof, the saidplug having openings in its sides and having within it a foraininous screen, and an automatic pressure valve carried by said bracket and communicating with the interior thereof.

3. In a bracket for use on int'eirnal com bu'stion engines, the combination Wltllt-WO: tubular an angle, of a tubularplug hav ng itsouter end closed and; its sides perforated entering one of said tubular parts at the angular bend of the bracket,-'and'an internal shoulder on said part against which the inner end of said tubular plugfits.

4:. In a bracket for use on internal combus tionengines, the combination with two tubular parts rigidly connected together at an angle, of a tubular plughaving its outer end closed and its sides perforated entering one of said tubular parts at the angular bend of the bracket, a screw threaded connection between said plug and bracket, an angular projection 011 the plug for facili:

t-ating removah 'a foraminous screen fitting;

within the tubular plug and covering the parts rigidly connected togetherfat perforations in the sides thereof, and an internal shoulder on said tubular part oflthe bracket against which the'inner end of said tubular plug fits.

In testimony whereof I alhx my signature in presence of two witnesses.
